STUMP-PULLER.

SPECIFIGATION forming part of Letters Patent No. 642,984, dated February 6, 1900.

Application filed March 21, 1899. Serial No. 709,992. (No model.) I

To ctZZ whom, it may concern:

Be it known that I, THOMAS EDGAR HOLT, a citizen of the United States, residing at Arlington, in the county of Carlisle and State of Kentucky, have invented a new and useful Stump-Puller,ofwhichthe followingisaspecification.

The subject of this invention is an improved stump puller or extractor; and the object thereof is to provide a device of this character capable of being conveniently transported from place to place when carrying an extracted stump, to provide a simplified, durable, and inexpensive structure by means of which a stump can be readily extracted, and to provide for the general efficiency and utility of a device of this character.

The invention consists in the features of construction hereinafter fully described,and pointed out in the appended claims.

In the accompanying drawings, forming a part of this specification, Figure 1 is a perspective view of a stump puller or extractor constructed in accordance with this invention. Fig. 2 is a horizontal section taken on a plane through the lifting-beam. Fig. 3 is a perspective view of the lifting-beam in detail.

The frame of thedevice comprises two sills or runners 1, upon which are mounted the upright guides 2, connected together at their upper ends by a cross-bar 3. The ends of the sills or runners 1 are provided with suitable hooks 4 or analogous devices for the attachment of means for drawing or transporting the puller or extractor, and the said upright guides preferably consist of two parallel rails or bars 5, securely fastened at their lower ends to the sills or runners 1 and at their upper ends to the cross-bar 3. The framework is completed and braced by the diagonal braces 6 and cross-braces 7, extending between said diagonal braces 6. In this way a strong and durable frame is furnished and, furthermore, one in which the diEerent parts can be made from ordinary timber and with a comparatively small degree of special preparation and labor.

The lifting-beam 8 consists, preferably, of a beam that is rectangular in cross-section and of greater length than the distance between the upright guides 2, so that each end of the beam projects beyond these guides, as shown in Fig. 1. The beam 8 is mounted in said guides and is free to move vertically therein, and each end portion thereof is provided with guide projections 9, situated adjacent tothe inner faces of the upright rails or bars 5, and which hold the beam against longitudinal movement with respect to said guides. The said guide projections are illustrated as pins extendingtransversely through the beam and projecting on both sides thereof, which aifords an effective and inexpensive construction. The beam is raised by means of jacks or screws 10, mounted upon sills or runners 1 just below the end portions of said lifting-beam and upon the upper ends 01' heads of which the end portions of the beam 8 normallyrest,so that by turning these jacks or screws 10 the lifting-beam 8 is raised or lowered.

The chain or cable 11, that is fastened to the stump to be extracted, is secured to the lifting-beam 8 about midway between its ends, and the central portion thereof is rounded, as shown at 12, to facilitate the fastening and operation of said cable. The said lifting-beam is also preferably rounded at its end portions and just inwardly of the guide projections 9, as shown at 13, for the attachment of cables 14, which pass upwardly and over the cross-bar 3 and then downwardly along the diagonal braces 6 at one side of the device to cleats 15, to which they are fastened. The cross-bar is provided with guides 16 for said cables, which in the instance illustrated are grooves or notches, as shown.

In use it will be understood that the stumppuller can be transported easily to the place where it is to be 0 erated and over the stump to be extracted, af or which the beam 8 is conveniently lowered into operative position, the cables 14 being unfastened. The chain or cable 11 is then securely fastened to the stump and the lifting-beam 8 raised by means of the jacks or screws 10 until the stump is dislodged and extracted, it being noted that by means of the cables 14 the lifting-beam 8 can be held securely at any elevation as the jackscrews are depressed or lowered. The oper ation is continued until the lifting-beam is sufficiently elevated to remove the stump.

The device is durable and inexpensive, as

before stated, since it can be constructed with ordinary timber and with comparatively little labor, and the operative parts are of simple construction, which not only makes it capable of being readily operated and also effective in its operation, but also reduces the liability of injury and inoperativeness to. a minimum and permits it to be easily and quickly repaired when necessary.

The jacks 10 maybe ordinary screw-jacks, as herein shown, or they may be hydraulic jacks. Any adapted form or character of lifting-jacksmay be employed. The cables 14 may be used to raise the beam 8 or to retain the same in elevated position, with the extracted stump suitably suspended during the transportation of the apparatus.

The apparatus may be drawn by horses, the books 4 serving for the attachment of draft devices.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A stump-puller, comprising a frame l1aving upright guides, a lifting-beam movable in said guides and projecting laterally beyond the same, lifting jacks mounted upon the frame and below the projecting end portions of said lifting-beam, independent means for holding said lifting-beam in an elevated position, and means for securing a stump thereto.

2. A stump-puller, comprising a frame having upright guides, a lifting-beam movable in said guides, means for raising said liftingbeam, cables connected with said liftingbeam and passing upwardly and over a portion of the frame, means for securing the free ends of said cables, and means for securing a stump to said lifting-beam.

3. A stump-puller, comprising a frame having upright guides, alifting-beam movable in said guides,lifting-jacks mounted upon said frame and engaging said lifting-beam, cables connected with said lifting-beam and passing upwardly and over a portion of the frame, means for securing the free ends of said cables, and means for securing a stump to said lifting-beam.

4. A stump-puller, comprising a frame having sills or runners and upright guides, a liftin g-beam movable in said guides and provided With guide means to hold the same against longitudinal movement, lifting-jacks mounted upon said sills and engaging said liftingbeam, cables connected with said lifting-beam and passing upwardly and over a portion of the frame, means for securing the free ends of said cables, and means for securing a stump to said lifting-beam. I

5. A stump-puller, comprising a portable frame mounted upon sills or runners and embodying upright guides, a lifting-beam movable in said guides, lifting-jacks operating upon the ends of the said beam to raise the same, and means for securing a stump to said beam.

6. A stump-puller, comprising a frame embodying a base portion from which projects a top portion having upright guides, a liftingbeam projecting between said guides and retained and guided thereby in its vertical movement, said beam being provided with means for securing a stump thereto, means carried by said base portion of the frame and operating upon the beam to raise the same between the vertical guides, and means independent of said raisin g-beam and carried upon the top portion of the frame and engaging the beam to retain the same in elevated position.

In testimony whereof I afilx my signature in presence of two witnesses.

THOMAS EDGAR HOLT.
